Anthopliora flavociiicia Huard. %. 



This is A. nigrocincta Provancher ; the name being a homonym, it 

 was changed to flavocinda by Huard (Nat. Can., Feb., 1897, p. 25). 

 I have a male, collected in California by Dr. Davidson, and had 

 formerly recorded the species as A. mdculifrons, to which it is cer- 

 tainly very closely allied, I have now seen>the types of maculifro7is, 

 and find Jiavocincta to differ by the darker tarsi, and the yellow reach- 

 ing the upper margin of the clypeus in the median line ; the apical 

 teeth of the abdomen are about as in maculifrons. The female from 

 Bear Valley, Calif., .which I had associated with the above male, 

 proves to belong to A. flexipes ; the second submarginal cell is much 

 broader below in liavocincta than in flexipes, and the males, of 

 course, have the legs entirely different. 



Anthopliora petrophila (Ckll.) 9. 



This was described as A. maculifrons petrophila , from Rock Creek, 

 Calif. It has the small apical triangle of hair on the fifth abdomi- 

 nal segment dark, and is really nearer to albata, of which it may be 

 considered a Californian representative. It differs from albata by 

 the decidedly yellow (not creamy) clypeal band, and also the broader 

 face. It is easily known from A. ciirta by the red flagellum. 



Anthopliora ansiriitheri ii. sp. (possibly flavocincta 9). — ?. 



Lengtli about 11 mm.; black, with abundant pale mouse-grey pubescence, wbich 

 on abdomen forms a dense felt-like surface, speckled with minute black (hair- 

 less) dots, but not failing at the bases of the segments, and so without any appear- 

 ance of black bands; hair of vertex, mesothorax and scutelluni with a moderate 

 amount of black intermixed; apical patch of hair on fifth abdominal segment 

 black and rather large ; small joints of tarsi reddish ; anteuuse black ; eyes green- 

 ish yellow; apical clypeal band chrome yellow, broad, not sending any process 

 upwards; a small transverse suiiraclypeal mark; tegulse pale reddish ; hair on 

 inner side of basal joint of hind tarsi black. 



Hah. — Los Angeles, California {Dr. Anstruther Davidson). Al- 

 lied to A. carta Prov., but larger, with the basis of the abdominal 

 segments not dark, and the abdominal hair slightly yellowish ; the 

 mandibles also are deeply bidentate, with the inner tooth large. 

 The color of the hair on the inner side of the hind tarsi is also quite 

 different. From ^.//e:i't/jes it is easily known by the fifth abnomi- 

 nal segment having only a black apical patch, instead of being all 

 black ; also by the black hair on vertex, and the absence of an 

 upward extension of the yellow clypeal band. From ^-1. albata it is
